Well there you have it... the two largest PC video game makers speaking out against Win8. Both companies already simultaneously develop for MacOS and Windows, and Valve is expressing sincere interest in Linux. Something is going to give... either Microsoft will realize it's shitty decisions with Win8 and make more desktop oriented SKUs, instead of forcing clunky and terrible tablet interfaces, or desktop gaming will move to another platform. In case of the latter I would prefer Linux over MacOS, though.
